Product Details

The LT3045 is a high performance low dropout linear regulator featuring LTC’s ultralow noise and ultrahigh PSRR architecture for powering noise sensitive applications. Designed as a precision current reference followed by a high performance voltage buffer, the LT3045 can be easily paralleled to further reduce noise, increase output current and spread heat on the PCB. The device supplies 500mA at a typical 260mV dropout voltage. Operating quiescent current is nominally 2.2mA and drops to <<1μA in shutdown.

Ultralow RMS Noise: 0.8μVRMS (10Hz to 100kHz)
Ultralow Spot Noise: 2nV/√Hz at 10kHz
